Mucoadhesive drug delivery systems stick to mucosal tissues and prolong the local retention time of drugs. Since the colon is covered by a mucosal layer, mucoadhesive rectal formulations may improve treatment of such diseases as hypertension or colon cancer. Ulcerative colitis (UC) is an inflammatory bowel disease characterized by chronic inflammation of the colonic mucosa. It is commonly treated with sulfasalazine (SSZ), which is metabolized by the intestinal flora into the therapeutic 5-aminosalicylic acid (5-ASA) and a toxic by-product sulfapyridine (SP)...

Kayexalate is an ion exchange resin that is commonly used to acutely treat patients with hyperkalemia. Bowel ulceration and necrosis is a rare and uncommonly recognized complication of kayexalate administration. More often, concomitant administration with sorbitol is reported to damage the bowel; however, there are reports of kayexalate administration causing bowel necrosis without sorbitol. We present a case of a critically ill patient who underwent total colectomy for colonic necrosis secondary to oral kayexalate administration that was not recognized until late in the pathologic process...

The human whole saliva is a vital body fluid to study the physiology and pathology of oral cavity. As a powerful technique for biomarker discovery, mass spectrometry-based proteomic strategy has been introduced to saliva analysis and identified hundreds of proteins and N-glycosylation sites. However, there still lacks of quantitative analysis, which is necessary for biomarker screening and biological researches. In this study, we established an integrated workflow by the combination of stable isotope dimethyl labeling, HILIC enrichment and high resolution mass spectrometry for both quantification of global proteome and N-glycoproteome of human saliva from oral ulcer patients...

Alterations of the oral cavity are common in children: 22% of children aged less than 4 years and 44% of those aged more than 12 develop dental erosion, 9-95% of children in Europe and in North America develop gingivitis, with adolescents showing a prevalence of more than 60% [Italian Ministry of Health, Guidelines 2013]. Alterations within the oral cavity can be the first sign of systemic diseases and may thus allow for an early diagnosis and treatment. In particular, being the oral cavity a part of the gastrointestinal system, oral alterations can be an expression of a gastrointestinal disease...

BACKGROUND: Recurrent aphthous stomatitis (RAS) is the most common painful ulcers of oral mucosal which can cause many sufferings. Treatment of RAS often includes administration of corticosteroids, analgesics and regulators of the immune system. However, considering the side effects of these medications, even their topical application must be done with caution. Alum is used in traditional medicine for treatment of oral ulcers without significant side effect. This study sought to assess the effect of topical application of alum on aphthous ulcers...

BACKGROUND: The treatment of Buruli ulcer (BU) that is caused by Mycobacterium ulcerans, is currently based on a daily administration of rifampin and streptomycin (RIF-STR). A fully oral intermittent regimen would greatly simplify its treatment on the field. METHODOLOGY/PRINCIPAL FINDINGS: The objective of this study was to assess the bactericidal and sterilizing activities of intermittent oral regimens in a murine model of established M. ulcerans infection. Regimens combining rifapentine (RFP 20 mg/kg) with either moxifloxacin (MXF 200 mg/kg), clarithromycin (CLR 100 mg/kg) or bedaquiline (BDQ 25 mg/kg) were administrated twice (2/7) or three (only for RFP-CLR 3/7) times weekly during 8 weeks...

The (13)C-urea breath test ((13)C-UBT), developed a few decades ago, is widely used as a non-invasive diagnostic method to detect only the presence of the gastric pathogen Helicobacter pylori infection; however, the actual disease state, i.e. whether the person harbouring H. pylori has peptic ulcer disease (PUD) or non-ulcerous dyspepsia (NUD), is still poorly understood. Nevertheless, the present (13)C-UBT has numerous limitations, drawbacks and pitfalls owing to the ingestion of (13)C-labelled external urea...
